The Carina Nebula, NGC 3372  A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy’s largest star forming regions. Like the smaller, more northerly the Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. The Carina Nebula is home to young, extremely massive stars, including the still enigmatic and violently variable Eta Carinae, a star system with well over 100 times the mass of the Sun. The Eta Carina is located in the upper center left of the image.  While Eta Carinae is likely on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory. Just to the right of the Eta Carina is the Keyhole, or Keyhole Nebula, is a small dark cloud of cold molecules and dust within the Carina Nebula, containing bright filaments of hot, fluorescing gas, silhouetted against the much brighter background nebula. The diameter of the Keyhole structure is approximately seven light-years . Its appearance has changed significantly since it was first observed, possibly due to changes in the ionizing radiation from Eta Carinae. The overall field of view here is about six moon diameters across. The image is a superposition of two separate images with the area around and above the keyhole a more detailed image done by the 17″ Planewave telescope. The image can be zoomed in to see the detail in this region. Another image next to this one in the Nebulae group shows the magnified view. These images complement true color versions seen in the True Color Nebulae collection.
